project tells us something about the distance and age of a far-away galaxy, bringing us one step closer to understanding how galaxies evolve. These volunteers met a major milestone this week: 200,000 classifications completed! 

That’s not all. The Redshift Wrangler project has received over 3,000 comments on Zooniverse talk boards, and has begun preparing a paper on their first batch of 11,000 galaxies. The paper will incorporate data from the DEep Imaging Multi-Object Spectrograph (DEIMOS) from NASA’s Keck Observatory Archive, as well as data from the Gemini and Subaru telescopes.

“NASA’s citizen science is a blessing, as I’ve found the Redshift Wrangler project to be such a rewarding experience,” said project volunteer, Baba Karthik Kalapatapu. “This project holds special meaning for me, as I had the unforgettable experience of visiting the Mauna Kea observatories, where I watched the Gemini North and Keck telescopes power on at sunset. I never could have imagined that I’d one day be working with data from those very telescopes—an incredible full-circle moment in my journey into understanding the cosmos.”
